Sophie Turner, best known for playing the badass that is Sansa Stark on Game of Thrones, has been cast as Mary Shelley in a dark gothic horror/romance based somewhat on the iconic author's life. I say somewhat because Turner will be playing a "monster," too.

...Mary Shelley's Monster tracks the young writer as she writes her seminal novel and is drawn into a Faustian bargain with her own "monster" of an alter ego, who offers literary fame at a desperate personal cost...

The real Shelley first published her Gothic horror classic Frankenstein anonymously at the age of 21 after marrying the poet Percy Bysshe Shelley. Monster envisions her life as "the story of the most extraordinary 19th century teenage heroine told in a visceral, sexy, contemporary way," per producer Rose Ganguzza, who produced last year's Beat Generation drama Kill Your Darlings. "Our film is not a period drama. It is a story of youth that transcends time, a gothic romance, a love triangle that involves a dark passenger and we are tremendously excited to have such an exciting cast onboard this wonderful project."

Yes, it seems Mary Shelley's Monster is doing a biography of the author of Frankenstein as a Dr. Jekyll and Mr. Hyde-type story? Which is really, really weird when you think about it.
